Five species of potoos occur in Ecuador, with Rufous Potoos (Nyctibius bracteatus) being one of the least known. We monitored a nest site of Rufous Potoos in a lowland forest in the Ecuadorian Amazon and provide information about the behavior of a nestling and one or more adults. Observations were conducted opportunistically from 10 August to 10 September 2018, and an infrared heat‐and‐motion activated camera was used to monitor the nest site from 11 September to 13 November 2018. We recorded 2006 10‐s videos of the nestling and/or adult(s) that we used to quantify behavior. The nestling spent most of its time perching (53%) and stretching (20.7%). Beginning when ~ 23 d old, the nestling began exercising its flight muscles and did so with increasing frequency over time. Adult behaviors included perching while brooding the nestling (55%), stretching (24%), flying (10.4%), and feeding the nestling (10.4%). The duration of the nestling period, ~ 2 mo, in our study was similar to that reported previously for this species. Our observations suggest that the breeding and nestling behavior of Rufous Potoos is similar to that of other Nyctibius species. However, additional studies are needed to better document the behavior of Rufous Potoos during the incubation period.

关于厄瓜多尔低地亚马逊地区红棕壤（Nyctibius bracteatus）的繁殖生物学注释

厄瓜多尔有五种potoos，其中有Rufous Potoos（Nyctibius bracteatus）是鲜为人知的之一。我们在厄瓜多尔亚马逊的低地森林中监视了红棕树的筑巢地，并提供了有关雏鸟和一个或多个成年人的行为的信息。于2018年8月10日至9月10日进行了机会性观察，并于2018年9月11日至11月13日使用了红外热动相机对巢穴进行了监测。我们记录了2006年10 s雏鸟和/或我们用来量化行为的成年人。雏鸟大部分时间都栖息在栖息处（53％）和伸展（20.7％）。从约23天大时开始，雏鸟开始锻炼其飞行肌肉，并且随着时间的推移频率不断增加。成年行为包括在孵化雏鸟时栖息（55％），伸展（24％），飞翔（10.4％）和喂养雏鸟（10.4％）。在我们的研究中，约2个月的筑巢期持续时间与先前针对该物种的报道相似。我们的观察结果表明，红棕树的繁殖和雏鸟行为与其他Nyctibius物种。但是，还需要进行其他研究才能更好地记录潜伏期期间红宝石的行为。
